HEADLIGHT.

Application filed october s, 1925. sei-mino. 60,283.

rl`his inventionrelates to improvementsin headlights and has for an importantobject thereof the provisionof means for cutting volf the glaring rays passing" from the upper portion of an automobile headlight which'is operative regardless of transverse inclination ofthe vehicle.

lt is well known that 4the ordinary headlight having a fixed translucent or modulatsection at the upper half of'its lens'is only operative as long as the vehicle is not transverselrinclined. Immediatedlfy upon inclination Vofthe vehicle, this section ceases to bethe upper half `of the headlight and consequently a; portion of the rays from the upper halfof the headlight during such inclination escape to dazzle the eyes of drivers of oncoming vehicles. Y

li. further object of thevinvention is to provide a device of this character which may be readily attached to headlights of the present construction without in any manner alteringv the same.

rThese and'other objects l attain by the construction shown inthe accompanying drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein o Figure '1V is a side elevation of a headlight having applied. thereto a glare shade constructed in accordance lwith my invention;

Figure 2 is a front elevation thereof;

Figurer 3' is a yvertical sectional view through the glare shade mounting;

Figure 4l is a transverse sectional view therethrough.

Referring jnow more particularly to the drawing, the numeral indicates an ordi- 'nary headlight/and 11 the illuminating element thereof which represents the axis of the headlight. 12 represents the usual retainingrim for the lens 13 ofthe headlight. ln accordance with my invention, l provide a journal boX lll having a bracket 15 shaped to conform to the sha-ping of the retaining rim 12 and secured thereto in such fashion that the bearing of the journal boX is disosed in vertical alignment with 'the axis of the headlight when Vin its normal position.

The journal box has a recess receiving a wooden bearing section 16 which, in turn, receives a shaft 17 the endsrof which are provided with flanges 18 preventing longitudinal movement of the shaft within the journal boX. One of these flanges has f light.

J: 1 l vl u v u. .y ioimed thereon, as an Yintegral extensiony thereof, a jaw 19 which'receives the upper edge of al glare shade 20. This glare shade 2O a substantially semi-circular. pla-,te of translucent or tinted glass and hasv .its loweredge 21 normally arranged ina horizontal plane includingV the axis` of the head The width of thisfglass at its lower edge is considerably greaterthan the diameter of the headlight lens so thatthe plate projects to opposite sides of the headlight7 as more clearly shown in Figure`2.

A cap 22 is provided for the journal box having a recess fof greatersizethan lthe shaft within which is arranged a wooden bearing block 23 and a metallic follower plate 2e bearing against this woodenl bearing block. The upper portion ofthe cap has a tubular boss`25, the yupper end of which is closedand has directed, therethrough an adjusting screw 26 which may.

be held in adjusted positions by a. lock nut 27. Between the inner end of this adjusting screw and a tit 28 formed upon the follower plate 24, a spring 29 isi" disposed, this spring togetherv with the adjusting screw providing a means for adjusting the tension with which the wood block 23 engages the shaft 17 and accordingly regulates the freedom of movement of this shaft and of the plate 20. lt additionally serves to prevent rattling noises during movements of the plate and shaft.

It will be obvious that during operation of the vehicle, there will be a tendency on the part of the plate to maintain its lower edge21 in horizontal position so that if the vehicle inclines transversely, the upper half of the rays of theheadlight are still Vout olf or modulated to such an extent that they are non-dazzling. It is pointed out that when the vehicle is making a turn, due to the present practice of banking the roads at the turn, such a transverse inclination of the vehicle takes place and accordingly with the ordinary headlight structure, an increased and more dazzling ray is passed from the headlight traveling directly across the road and accordingly interferes with Vthe operation of vehicles passing in the opposite direction. In my device, howj ever, this tendency of the rays to increase in strength is eliminated. lt is pointed out that the structure hereinbefore described, while described and illustrated as applied to the headlights of yan automobile could quite as conveniently be applied to the headlight of a locomotive and would perform the same functions in exactly the same manner.

Since the construction hereinbefore set forth is obviously capable of a certain range of change and modilication Without materially departing from the spirit of the invention, l do notlimit myself to such specie structure except as hereinafter claimed.

I claim:

1.111 combination With a headlight, a journal box supported from the headlight at the upper edge thereof, a shaft in said journal box and provided with a jaw, a. translucent panel Within the jaw and having its lower edge in horizontal alignment with the horizontal axis of the headlight, said panel being substantiallyv in the torni of a semi-circular segment having a diametral Width greater than the diameter of the lens of the headlight.

In combination With a headlight7 a journal box supported from the headlight at the upper edge thereof, a shaft in said journal box and provided With a jaw, a translucent panel Within the jar.7 and having its lower edge in horizontal alignment Vith the horizontal axis of the headlight,

said panel being substantially in the form of a semi-circular segment having a 'diametral Width greater than the dian'leter of the lens of the headlight and means associated With the journal box for braking the shaft.

3. In combination with a headlight, a freely rotatable rock shalt arranged above and paralleling the horizontal axis of the headlight, a translucent panel secured to the sha'lt and extending in the path ot the upper halt of the rays of' the headlight and of greater width than said headlight and means associated with the shalt for ln'aking the shatt to prevent undue oscillation of said panel.

et. In combination with a headlight, a support at the upper end of the headlight, a translucent panel mounted upon the sup port to swing in a plane paralleling the lens of the headlight extending into the path et the rays ot the headlight passing through the upper half of the lens thereof, said panel being substantialljv semi-circular and haring a diameter greater than the diameter ot' the lens.

ln testimonjv whereof l hereunto atiix my signature.
